Why Is DRS Being Replaced by MOM in F1? New regulation

DRS vs MOM
  • By Dr. AK Rana

Let’s talk about how Formula 1 is reinventing overtaking from 2026! DRS is going out, and MOM is coming in.

But what’s the real difference?

Let’s break it down:

What is DRS (Drag Reduction System)?

DRS was introduced in 2011.

It opens a flap on the rear wing to reduce drag.

Only used in special DRS zones if you’re within 1 second of the car ahead.

Helps you go 10–12 km/h faster on straights.

Physics:

Less drag = more speed.

But also = less downforce, so the car can feel unstable

Implication:

DRS made overtaking easier, but many fans felt it made things too predictable.

What is MOM (Manual Override Mode)?

From 2026, DRS is gone.

MOM replaces it.

MOM is Formula 1’s fresh approach to overtaking for 2026. Instead of relying on a movable rear wing, drivers will now have a manual override to unlock additional electrical power for overtaking.

This taps into the hybrid engine’s electric side, providing a short power boost that the driver can control.

How it works:

MOM gives the pursuing driver access to more battery power for a limited time.

The defending driver cannot use the same boost while being attacked.

Physics:

Electric motors = instant torque = faster acceleration.

No change in aerodynamic profile, so cars stay stable through fast corners.

What is Active Aerodynamics?

Along with MOM, 2026 F1 cars will feature active aerodynamics. These allow the wings to adjust based on driving conditions:

“Z-mode” for high downforce in corners.

“X-mode” for low drag on straights.

Unlike DRS, these wing changes are not for overtaking, but for efficiency and handling.

They will be driver-activated but in a more controlled, symmetrical way.

DRS vs MOM – Quick Comparison

Tech Used:

DRS = rear wing flap

MOM = electric power boost

Activation:

DRS = limited zones

MOM = flexible, driver-controlled

Effect:

DRS = lower drag

MOM = more power, instant torque

Stability:

DRS = less stable in corners

MOM = stable, no aero change

Style:

DRS = often predictable

MOM = more strategic

What Does This Mean for Racing?

✅ More driver skill: With MOM, drivers will need to plan their overtakes, manage energy deployment, and choose the right moment.

✅ Cleaner battles: Active aero and MOM won’t alter car balance mid-corner like DRS sometimes did. Expect tighter, wheel-to-wheel action.

⚠️ Potential downside? Battery power is limited. If overused early, drivers might run out of boost late in the race.

F1’s switch from DRS to MOM isn’t just technical – it’s about giving more power back to the drivers.

It’s cleaner, smarter, and definitely more exciting!

2026 will be a whole new game 🏁
